NSIDC’s IceBridge Data Management
Project goals: Ensure preservation of dataIncrease and broaden usageof data
Project tasks:
Provide access to related data that is safely archived elsewhere
Data brokering
Also archive flight reports; Level 0 data; ancillary data; broad scope of pre-IceBridge data
Data archive - ongoing flight campaign data - pre-IceBridge data
Portal with map-based access using geometry of flight lines; data readers, documentation, …
Tools & services
Compiled data sets for streamlined analysis
Value-added products

Tools and Services
NSIDC provides a wide range of supporting services
-Documentation- detailed user guide for each data set
-User Services Office- personal service via email or phone, with backup support from
NSIDC programmers/scientists and instrument teams-Software for reading and interpreting data files-Data access portal (in work)
- Web-accessible map-based interface to all available data- Planned comprehensive filtering by instrument/spatial/temporal
parameters; easy access to data

IceBridge Data Access Portal
First release June 2011 with access to flight lines and flight reportsFrequent iterative releases for access to instrument data and value-added productsAdditional features will be user-driven
8 European Geosciences Union, CR3.10April 4, 2011
Value-Added Products: Goals-Process flight data to extract and calculate useful parameters for faster analysis
-Update compiled gridded data sets (DEMs, bedrock elevation maps) rapidly
-Facilitate the integration of newscience algorithms into routine data distribution
Two classes of Products: Along-Track Products – flightline tables of multiple sensor values and images, and multi-sensor derived values
Gridded Products – post-campaign rapid updating of surface elevation DEMs, dH/dt grids, and bed elevation
9 European Geosciences Union, CR3.10April 4, 2011
Value-Added Products
-Aligned (time and location) data sets, and pre-calculated parameters –All these data sets and derived parameters are co-located–
Along-track product examples: Surface Properties Table
Snow radar data image +Two layer picks (VAP)
Snow thickness between layer picks (VAP)
Subset of digital camera
Subset of Laser altimeter
Imagehistogram(VAP)
